PROBLEM TO BE SOLVED: To provide a substance container which can be easily transported, installed and stored and which can cause a chemical reaction by a simple operation. A container body (3), a partition member (5) provided inside the container body (3) for partitioning the inside of the container body (3) into a first space (9) and a second space (11), and a first space (9). And a second substance contained in the second space 11. The partition member 5 is deformed by applying an external force, and the first substance and the second substance are separated from each other. A substance container 1 configured to cause a chemical reaction. [Selection diagram] Figure 1【課題】運搬や設置や保管が容易であって、簡単な操作で化学反応を起こすことができる物質収容器を提供する。【解決手段】容器本体３と、容器本体３の内部に設けられ容器本体３内を第１の空間９と第２の空間１１とに仕切っている仕切り部材５と、第１の空間９に入っている第１の物質と、第２の空間１１に入っている第２の物質とを有し、外力を加えることで、仕切り部材５が変形し、第１の物質と第２の物質とが化学反応を起こすように構成されている物質収容器１である。【選択図】図１
